[PATCH 0/2] Compiler Attributes: __fallthrough

[Miguel Ojeda <miguel.ojeda.sandonis@gmail.com>]

These are two patches are meant to go on top of the rest of the compiler
attributes series on:

  https://github.com/ojeda/linux/tree/compiler-attributes

which will be sent to Greg for the next merge window.

Please review them and let me know! (specially if someone is against
__fallthrough for some reason :-).

The first patch introduces the attribute and gives the rationale.
The second patch is an example of usage.

This was started in the following thread:

  https://lore.kernel.org/lkml/20181017062255.oiu44y4zuuwilan3@mwanda/

Cheers,
Miguel
